Addon C10 Mk II

3 x multiroom.

A heavy weight champion of multiroom HiFi performance as well as compatibility with AirPlay 2 and Google Cast. Still compact and easy to place, but this speaker packs a real punch. C10 MkII offers multiroom listening via Audio Pro multiroom system, but also via Google Cast and AirPlay 2.

Set this up as stereo paired with prior version c10, play through Spotify. Works great, sounds great.


Music sounds so good over Spotify Premium! I just wish it had a 3.5mm input jack for things like connecting to computers/monitors that don’t have speakers. There is a L and R (white and red) audio in which is fine just requires another cable, just no generic 3.5mm audio in for ease of use when quality isn’t that important. Not a deal breaker though still 5/5 from my noob (aka not audiophile) experience!

The sound is as good as advertised – remarkable reproduction for such a small box.

Once the unit is tied into a network (not exactly the most direct process until a few tries), it responds well to airplay, which is my principal wireless source and the reason I chose this edition.

One rough edge: Is it impossible to differentiate the C10 Mk II from other networked devices? If not, it would be a great upgrade to the next firmware version.

The app is primitive and the channel buttons are useless unless one subscribes to one of the affiliated services, which I do not.

All-in-all, a superior product. Thank you.


I returned the C10 MKII. The sound was clean and the presence was good. However, to me music sounded buried and non-lively for lack of better terms. My first wireless speaker years ago was the Definitive Technology W7. In its class of wireless mono speakers, although, it does not have the broad lower end due to its diminutive size, sounds energetic and pleasing. All the music sounds forthright. Must have a remarkable DSP to produce such volume with the right balance of instrumental and vocal reproduction.

What hobbles the W7 is DTS Play-fi. Plex is a must and only Chromecast, Sonos and Airplay can utilize the Plex app. With my experience with Sonos and Chromecast, Airplay 2 by far is the most convenient method of casting music due to the fact that Airplay is baked into the OS.

I was hoping the MKII with Airplay 2 would be the ultimate go to speaker to place in various locations in the house but to me the W7 sounds better. My current solution is the Bluesound Pulse 2I with onboard volume controls and Airplay 2. I now have 2 of these attached to W7 speakers. For now my main Meridian active speakers have an Airport Extreme with Airplay 2 attached to them. In the future I plan on a third Pulse 2I for onboard volume control. The great thing about the 2I I can upgrade to better active speakers of my choice anytime I want to.

If Audio pro has never experienced a W7 I suggest you locate one for evaluation. The W7 is no longer in production but I’m sure there are used ones still available.

The below list are speakers I have auditioned over the years looking for a single solution to a worthy sounding speaker with onboard volume control with Plex access and most recently for me, Airplay 2 is a must. Most of these speakers sound atrocious.

Product is good in clarity and sonic balance but the 80W rating seems misleading. It is not loud enough to replace a home stereo but a very good desktop source if music
